The AHsupply kit would probably be easier to start with. If the ballast ever goes out, you can replace it with one of the HD or Lowes ballasts. I seriously doubt that anyone working in their lighting dept knows what the ballasts will light other than whats printed on the ballast. I have several of them running PC
's now and they work just as well as any other. I build my own reflectors so the only thing I have to order is the endcaps. I usually order them from www.il-solutions.com
...best price I've found on them. I don't get the moisture proof ones as I don't think they're worth the extra money.
